===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:

I am delighted that one of my first official duties at John Hancock Funds is to
welcome you to the New Millennium! I wish you all the best for a century filled
with momentous occasions.

Every New Year, of course, provides us with a built-in opportunity to make new
resolutions, or re-commit to old ones. It seems fitting, therefore, that this
special New Year 2000 coincides with a very important, although certainly less
exotic, event.

Starting last October, personalized Social Security statements are being sent to
125 million workers over age 25, showing estimates of the retirement, disability
and survivor benefits that they and their families are eligible to receive now
and in the future.

The statements, to be sent out annually, will provide people with a glimpse of
what they can expect from the government when they retire. This should be
comforting to those who feared that Social Security wouldn't be there for them
at all. But many people also already know that government benefits will only
fulfill a small piece of their retirement needs.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman and Chief Executive Officer,
flush right next to fourth paragraph.]
- --------------------------------------------------------------------------------

The best thing about this massive mailing is that it can serve as a wake-up call
to encourage families to focus more on planning for their financial future.

When you receive your statement, expected to be within three months of your next
birthday, we urge you to read it carefully for accuracy, making sure your annual
earnings history and amounts you have contributed over the years are correct.
Keep in mind that the estimated benefits are precisely that, and that rules and
regulations may change by the time you retire. Also remember that they are not
inflation adjusted, so it would be unrealistic to expect them to have the same
purchasing power in the future as they would today.

We also encourage you to use this mailing as a reason to contact your investment
professional, or to select one if you are not working with somebody. He or she
can help you focus on establishing and maintaining a sound plan to achieve a
comfortable retirement. Together, you should make sure to maximize your
participation in tax-advantaged programs like IRAs and 401(k)s.

The stakes are too high to leave your retirement lifestyle to chance. Congress'
awareness-raising effort is commendable. The next step is yours. Mark the
beginning of the New Millennium by taking it.

Sincerely,


/s/ MAUREEN R. FORD

               Bonds struggle in rising interest-rate environment
- --------------------------------------------------------------------------------

Bond investors endured a difficult six months. The U.S. economy remained
surprisingly robust and economies worldwide stabilized or came back to life, so
fears grew that inflation would re-emerge. What's more, the price of oil spiked,
along with those of other commodities. This combination caused interest rates to
rise and bond prices to fall during much of the period. In addition, the Federal
Reserve raised short-term rates three times between June and November to try to
cool off the economy and prevent an outbreak of inflation. U.S. Treasury bonds,
which are the most sensitive to interest-rate moves, were especially hard hit.

   High-yield bonds, those rated below investment grade, fared slightly better
than Treasuries, as their higher yields helped them better offset the effect of
price declines. Nonetheless, high-yield bonds had their own set of issues,
starting with an increased number of earnings disappointments and debt defaults.
Demand also fell significantly, as investors turned their attentions to the
high-flying technology sector of the stock market. At the same time, supply
remained fairly high, because many corporations had issued new bonds earlier in
the year to lock in still relatively low rates and avoid potential Y2K problems
later.

Fund performance

For the six months ended November 30, 1999, John Hancock High Yield Bond Fund's
Class A, Class B and Class C shares posted total returns of

1.31%, 0.92% and 0.92%, respectively, at net asset value. That compared to the
- -0.37% return of the average high current yield fund, according to Lipper, Inc.1
Keep in mind that your net asset value return will be different from the Fund's
performance if you were not invested in the Fund for the entire period and did
not reinvest all distributions. Historical performance information can be found
on pages six and seven.

Paper, energy rebound

Rising oil prices and rebounding Asian economies boosted our cyclical companies,
whose fortunes are closely tied to moves in the economy. Our energy and paper
companies were two areas of strength over the last six months, as they came back
from their lows hit in last year's global turmoil.

   Our bond and stock holdings in Key Energy Group -- our largest company
position -- rebounded as rising oil prices sparked a wave of new drilling,
fueling demand for the type of well-maintenance services that Key Energy
provides. The same held true for Weatherford, which supplies parts to
natural-gas drillers, and we took profits. We also sold our bonds in natural-gas
driller Grey Wolf. Because we still like the company, we took advantage of the
Fund's ability to own a limited amount of stock to buy Grey Wolf's stock, where
we believe the upside now lies.

   Canadian paper company Repap New Brunswick did well as paper prices rose
along with Asian demand, which had virtually dried up during Asia's near
depression last year. Asia Pulp and Paper (APP), the world's lowest-cost paper
provider, also rebounded. Consolidation remains a driving theme in the paper
industry, which we like. One result has been less capacity, which has enabled
the remaining players to raise prices, especially now, when there is no
expectation of new supply coming on line.

Avoiding trouble

Individual security selection was an important factor for us this period --
especially the names we avoided. The number of high-yield companies that failed
to execute their business plans rose during 1999, including such high-profile
names as Iridium and Fruit of the Loom, neither of which we owned. We
sidestepped the worst of the troubles, but not entirely. By definition,
companies rated below investment grade are subject to a greater risk of defaults
and earnings disappointments. Regal Cinemas was an example this period, although
fortunately our stake there is quite modest. Another disappointment was
Integrated Health Services, which was stung by questions about billing practices
in Florida, as well as by industry concerns about the potential for further
reductions in Medicare reimbursements.

Better quality and value overseas

In contrast to the saturated U.S. market, we are now finding better quality and
value overseas. As a result, we increased our foreign stake to 20% of the Fund's
net assets, up from 16% six months ago. In particular, we added or boosted our
stakes in telecommunications, paper and energy companies. Our biggest positions
are a 4% stake in Canada and 5% in the United Kingdom. In fact, our foreign
holdings were a big contributor to our out performance this period, because
their prices were more steady, at the same time that we continued to earn an
attractive level of current income. Our Fuji Bank preferred stock rose as Japan
implemented financial reforms, and we took profits and pared our stake.
Brazilian company Trikem, a producer of PVC tubing, also did well.

   In addition to the foreign paper and energy securities we mentioned earlier,
we also had good results from our telecommunications names. One was VersaTel
Telecom International, a Dutch phone company providing voice, data and Internet
transmission service to small and mid-sized business in Europe, where phone
service remains sub-par and demand for the newest technology is growing rapidly.
Another solid performer was Omnipoint, which was recently taken over by
VoiceStream, as merger and acquisition activity heats up among telecom
companies. We will continue to use our ability to invest overseas to take
advantage of the opportunities that arise as foreign high-yield bond issuance
continues to grow, which is currently happening in Western Europe.

A look ahead

We are keeping our cautiously optimistic outlook for high-yield bonds. After
struggling last year, they continue to present very attractive values and income
streams. Yet we believe individual credit selection is becoming more important
than ever. Nowhere is that more apparent than in the burgeoning telecom
industry, where many companies have been formed in the last several years in the
wake of industry deregulation. What's more, should the U.S. economy slow too
much, it will become more difficult for high-yield companies with aggressive
business plans to reach their earnings targets. We will continue to apply our
in-depth fundamental analysis toward finding companies worth the extra risk we
are taking to own them.

"...individual credit selection is becoming more important than ever."

                              A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock High Yield Bond Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 4.5%. Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 4.75%. Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years). Class C
performance includes a contingent deferred sales charge (1% declining to 0%
after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - High Yield Bond Fund

(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Bond Trust (the "Trust") is an open-end management investment
company, registered under the Investment Company Act of 1940. The Trust consists
of three series: John Hancock High Yield Bond Fund (the "Fund"), John Hancock
Intermediate Government Fund and John Hancock Government Income Fund
(collectively, the "Funds"). The other two series of the Trust are reported in
separate financial statements. The investment objective of the Fund is to
maximize current income without assuming undue risk by investing in a
diversified portfolio consisting primarily of lower-rated, high-yielding debt
securities such as: domestic and foreign corporate bonds; debentures and notes;
convertible securities; preferred stocks; and domestic and foreign government
obligations. As a secondary objective, the Fund seeks capital appreciation, but
only when it is consistent with the primary objective of maximizing current
income.

   The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights to voting, redemptions, dividends and liquidation, except that
certain expenses, subject to the approval of the Trustees, may be applied
differently to each class of shares in accordance with current regulations of
the Securities and Exchange Commission and the Internal Revenue Service.
Shareholders of a class which bears distribution and service expenses under
terms of a distribution plan have exclusive voting rights to that distribution
plan.

   Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Board of Trustees. Short-term debt investments maturing within
60 days are valued at amortized cost, which approximates market value. All
portfolio transactions initially expressed in terms of foreign currencies have
been translated into U.S. dollars as described in "Foreign Currency Translation"
below.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. Aggregate cash balances
are invested in one or more repurchase agreements, whose underlying securities
are obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $21,790,325 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. To the extent that such carryforwards are used by
the Fund, no capital gain distributions will be made. The carryforwards expire
May 31, 2007. Additionally, net capital losses of $16,464,424 attributable to
security transactions incurred after October 31, 1998 are treated as arising on
the first day (June 1, 1999) of the Fund's next taxable year.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Dividend income on investment securities
is recorded on the ex-dividend date or, in the case of some foreign securities,
on the date thereafter when the Fund is made aware of the dividend. Interest
income on investment securities is recorded on the accrual basis. Foreign income
may be subject to foreign withholding taxes, which are accrued as applicable.

   The Fund records all distributions to shareholders from net investment income
and realized gains on the ex-dividend date. Such distributions are determined in
conformity with income tax regulations, which may differ from generally accepted
accounting principles.

<PAGE>

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - High Yield Bond Fund

Dividends paid by the Fund with respect to each class of shares will be
calculated in the same manner, at the same time and will be in the same amount,
except for the effect of expenses that may be applied differently to each class.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are calculated at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative sizes of the funds.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
from either the date of issue or date of purchase over the life of the security,
as required by the Internal Revenue Code.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund entered into a
syndicated line of credit agreement with various banks that enables the Fund to
participate with other funds managed by the Adviser in an unsecured line of
credit with banks which permit borrowings up to $500 million, collectively.
Interest is charged to each fund, based on its borrowing. In addition, a
commitment fee based on the average daily unused portion of the line of credit
is allocated among the participating funds. The Fund had no borrowing activity
for the period ended November 30, 1999.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative and/or to hedge against the effects of fluctuations in
interest rates and other market conditions. Buying futures tends to increase the
Fund's exposure to the underlying instrument. Selling futures tends to decrease
the Fund's exposure to the underlying instrument or hedge other Fund
instruments. At the time the Fund enters into a financial futures contract, it
will be required to deposit with its custodian a specified amount of cash or
U.S. government securities, known as "initial margin," equal to a certain
percentage of the value of the financial future contract being traded. Each day,
the futures contract is valued at the official settlement price of the board of
trade or U.S. commodities exchange on which it trades. Subsequent payments to
and from the broker, known as "variation margin," are made on a daily basis as
the market price of the financial futures contract fluctuates. Daily variation
margin adjustments, arising from this "mark to market," are recorded by the Fund
as unrealized gains or losses.

   When the contracts are closed, the Fund recognizes a gain or loss. Risks of
entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange.

   For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures transactions.

   At November 30, 1999, there were no open positions in financial futures
contracts.

OPTIONS Listed options are valued at the last quoted sales price on the exchange
on which they are primarily traded. Over-the-counter options are valued at the
mean between the last bid and asked prices. Upon the writing of a call or put
option, an amount equal to the premium received by the Fund is included in the
Statement of Assets and Liabilities as an asset and corresponding liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the written option.

   The Fund may use option contracts to manage its exposure to the stock market.
Writing puts and buying calls tend to increase the Fund's


                                       30
<PAGE>

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - High Yield Bond Fund

exposure to the underlying instrument and buying puts and writing calls tend to
decrease the Fund's exposure to the underlying instrument, or hedge other Fund
investments.

   The maximum exposure to loss for any purchased options will be limited to the
premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value reflects the maximum exposure of
the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

   Risks may also arise if counterparties do not perform under the contract's
terms ("credit risk"), or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit risk and liquidity risks in over-the-counter option contracts, the Fund
will continuously monitor the creditworthiness of all its counterparties.

   At any particular time, except for purchased options, market or credit risk
may involve amounts in excess of those reflected in the Fund's period-end
Statement of Assets and Liabilities.

   At November 30, 1999, there were no written option transactions.

FOREIGN CURRENCY TRANSLATION All assets and liabilities initially expressed in
terms of foreign currencies are translated into U.S. dollars based on London
currency exchange quotations as of 5:00 P.M., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain/(loss) on investments are
translated at the rates prevailing at the dates of the transactions.

   The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

   Reported net realized foreign exchange gains or losses arise from sales of
foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains or losses arise from changes in the
value of assets and liabilities other than investments in securities at fiscal
year end, resulting from changes in the exchange rate.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS The Fund may enter into forward
foreign currency exchange contracts for speculative purposes and/or as a hedge
against the effect of fluctuations in currency exchange rates. A forward foreign
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date at a set price. The aggregate principal amounts of the
contracts are marked to market daily at the applicable foreign currency exchange
rates. Any resulting unrealized gains and losses are included in the
determination of the Fund's daily net assets. The Fund records realized gains
and losses at the time the forward foreign currency contract is closed out or
offset by a matching contract. Risks may arise upon entering these contracts
from potential inability of counterparties to meet the terms of the contract and
from unanticipated movements in the value of a foreign currency relative to the
U.S. dollar.

   These contracts involve market or credit risk in excess of the unrealized
gain or loss reflected in the Fund's Statement of Assets and Liabilities. The
Fund may also purchase and sell forward contracts to facilitate the settlement
of foreign currency denominated portfolio transactions, under which it intends
to take delivery of the foreign currency. Such contracts normally involve no
market risk if they are offset by the currency amount of the underlying
transaction.

NOTE B -
MANAGEMENT FEE AND TRANSACTIONS
WITH AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.625% of the first $75,000,000 of the Fund's
average daily net asset value, (b) 0.5625% of the next $75,000,000 and (c) 0.50%
of the Fund's average daily net asset value in excess of $150,000,000.

   The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the period ended November
30, 1999, net sales charges received with regard to sales of Class A shares
amounted to $211,477. Out of this amount, $41,487 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $82,801
was paid as sales commissions to unrelated broker-dealers and $87,189 was paid
as sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Signator Investors.

   Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended November 30,
1999, contingent deferred sales charges paid to JH Funds amounted to $1,533,459.

   Class C shares which are redeemed within one year of purchase will be subject
to a CDSC at a rate of 1.0% of the lesser of the current market value at the
time of redemption or the original purchase cost of the shares being redeemed.
Proceeds from the CDSC are paid to JH Funds and are used in whole or in part to
defray its expenses related to providing distribution related services to the
Fund in connection with the sale of Class C shares. For the period ended
November 30, 1999, contingent deferred sales charges paid to JH Funds amounted
to $15,228.

   In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.25% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

                    John Hancock Funds - High Yield Bond Fund

   The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The Fund pays
transfer agent fees based on the number of shareholder accounts and certain
out-of-pocket expenses.

   The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

   Mr. Stephen L. Brown, Ms. Maureen R. Ford, Ms. Anne C. Hodsdon and Mr.
Richard S. Scipione are trustees and/or officers of the Adviser and/or its
affiliates, as well as Trustees of the Fund. The compensation of unaffiliated
Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer for
tax purposes their receipt of this compensation under the John Hancock Group of
Funds Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation liability
are recorded on the Fund's books as an other asset. The deferred compensation
liability and the related other asset are always equal and are marked to market
on a periodic basis to reflect any income earned by the investment as well as
any unrealized gains or losses. The investment had no impact on the operations
of the Fund.

===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:

I am delighted that one of my first official duties at John Hancock Funds is to
welcome you to the New Millennium! I wish you all the best for a century filled
with momentous occasions.

Every New Year, of course, provides us with a built-in opportunity to make new
resolutions, or re-commit to old ones. It seems fitting, therefore, that this
special New Year 2000 coincides with a very important, although certainly less
exotic, event.

Starting last October, personalized Social Security statements are being sent to
125 million workers over age 25, showing estimates of the retirement, disability
and survivor benefits that they and their families are eligible to receive now
and in the future.

The statements, to be sent out annually, will provide people with a glimpse of
what they can expect from the government when they retire. This should be
comforting to those who feared that Social Security wouldn't be there for them
at all. But many people also already know that government benefits will only
fulfill a small piece of their retirement needs.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman and Chief Executive Officer,
flush right next to fourth paragraph.]
- --------------------------------------------------------------------------------

The best thing about this massive mailing is that it can serve as a wake-up call
to encourage families to focus more on planning for their financial future.

When you receive your statement, expected to be within three months of your next
birthday, we urge you to read it carefully for accuracy, making sure your annual
earnings history and amounts you have contributed over the years are correct.
Keep in mind that the estimated benefits are precisely that, and that rules and
regulations may change by the time you retire. Also remember that they are not
inflation adjusted, so it would be unrealistic to expect them to have the same
purchasing power in the future as they would today.

We also encourage you to use this mailing as a reason to contact your investment
professional, or to select one if you are not working with somebody. He or she
can help you focus on establishing and maintaining a sound plan to achieve a
comfortable retirement. Together, you should make sure to maximize your
participation in tax-advantaged programs like IRAs and 401(k)s.

The stakes are too high to leave your retirement lifestyle to chance. Congress'
awareness-raising effort is commendable. The next step is yours. Mark the
beginning of the New Millennium by taking it.

Sincerely,


/s/ Maureen R. Ford

          Inflation fears and rising interest rates hamper bond market

The bond market was volatile in the second half of 1999, as investors reacted to
growing inflation concerns and anticipated that the Federal Reserve's response
would be to raise short-term interest rates. Both were cause for worry --
inflation because it erodes the value of the fixed interest earned on bond
investments and rising interest rates because they mean falling bond prices. The
Federal Reserve ended up boosting interest rates three times between June and
November for a total increase of three-quarters of a percentage point. Bond
yields also climbed higher, with the yield on the 30-year Treasury moving from a
low of 5.82% at the end of May to a high of 6.38% in late October. By the end of
November, the 30-year yield stood at 6.29%.

      Inflation fears stemmed initially from the economy's strong growth, which
continued unabated throughout the second half. In addition, unemployment reached
4.1%, its lowest level in 30 years, increasing wage pressures. Commodity prices,
especially oil, strengthened. And economies in both Asia and Europe began to
pick up, removing the deflationary effect that had helped keep U.S. economic
growth somewhat in check in recent years. As economies in emerging markets began
improving, the flight to quality that had propelled so many investors into U.S.
Treasuries came to an end. In the face of rising interest rates, investors
favored bonds with a yield advantage over Treasuries, including both mortgage

bonds and U.S. government agencies. For the six months ended November 30, 1999,
the Lehman Brothers Mortgage-Backed Securities Fixed-Rate Index returned 1.21%,
ahead of the Lehman Brothers Treasury Index's 0.40% return.

Performance review

Fortunately, John Hancock Government Income Fund had a high stake in bonds with
a yield advantage over Treasuries, known as spread products. For the six months
ended November 30, 1999, the Fund's Class A, Class B and Class C shares returned
0.10%, -0.26%, and -0.28%, respectively, at net asset value. By comparison, the
average general U.S. government income fund returned -0.25% over the same
period, according to Lipper, Inc.1 Keep in mind that your net asset value return
will be different from the Fund's performance if you were not invested in the
Fund for the entire period and did not reinvest all distributions. For
longer-term performance information, please see pages six and seven.

Higher spread stake

By the end of November, the Fund had 78% of its net assets in spread products,
including mortgages issued by U.S. government agencies and U.S. government
agencies themselves. In the mortgage sector, which totaled about 63% of net
assets, we made few changes. We had already added substantially to our mortgage
stake in late 1998 and early 1999 when prices were cheap. At the time, we had
bought mostly GNMAs with current coupons (or stated interest rates) of 6% or
6.5% because they offered the least prepayment risk -- the risk that homeowners
would pay off their mortgages early. In addition, we continued to hold on to our
12% stake in collateralized mortgages (CMOs) -- bonds that separate the cash
flows of mortgage pools into various classes with different maturities. By
contrast, we boosted our investment in non-mortgage U.S. government agencies to
15% of net assets, up from 10% six months earlier. We bought both callable and
non-callable agencies with five- and ten-year maturities. We favored callables
- -- bonds that the issuer can call or redeem before maturity -- because of their
slight yield advantage over non-callables.

Lower interest rate risk

As interest rates rose, we cut back on 30-year Treasuries. We did this because
the Treasury sector is especially sensitive to changes in interest rates. We
also knew that rising interest rates would make long maturity bonds less
attractive. That left us with some 20-year Treasuries, as well as some
intermediate-term callable Treasuries. By trimming long-term Treasuries, we were
able to cut the Fund's duration -- a measure of how sensitive the Fund is to
changes in interest rates -- from 5.3 years to 5.1 years. The shorter a bond's
duration, the less its price will fall as interest rates rise -- or rise as
interest rates fall. The Fund's duration, however, was still slightly longer
than average, which hindered performance.

More interest rate hikes

We expect the recent interest-rate hikes to slow the economy modestly, but not
enough to eliminate inflation concerns. As a result, we believe there will be
more interest-rate increases in the new year. The Federal Reserve used to be
able to raise interest rates and slow the economy. But consumption is now a main
driver of the economy, led primarily by the wealth accumulated through the stock
market and retirement plans. The four-month trailing gross domestic product
number -- a measure of economic growth -- has remained around 4.3% for a while
now. Forecasts are that fourth quarter GDP may come in even higher, given the
strong start to holiday spending.

      We expect the bond market to remain volatile, given inflation fears and
the uncertainty surrounding the Fed's next move. The bond market is fear-driven,
not reality-driven. The reality is that the Fed interest-rate hikes are keeping
inflation under control, which is positive for long-term bond investors. Our
strategy in this rising-rate environment will be to continue to maintain a high
stake in spread products. We may make some adjustments in what we own,
exchanging some of our current mortgage bonds for ones with slightly higher
coupons. We also plan to keep a neutral or average duration, currently around
5.0 years. Finally, we're taking a long-term view, believing that the pain
caused by the Fed's decisions today could eventually result in gains for bond
holders who stay the course.

                   John Hancock Funds - Government Income Fund

- --------------------------------------------------------------------------------
                              A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Government Income Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 4.5%. Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 4.75%. Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years). Class C
performance includes a contingent deferred sales charge (1% declining to 0%
after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

Notes to Performance

(1) Effective December 4, 1998, the Adviser agreed to limit the Fund's
    management fee to 0.50% of the Fund's daily net assets. Without the
    limitation of expenses, the average annual total return for the one-year
    period, five-year period and since inception would have been (6.67%), 6.11%
    and 6.11%, respectively, for Class A shares. The average annual total return
    for the one-year period, five-year period and ten-year period would have
    been (7.55%), 6.02% and 6.45%, respectively, for Class B shares. The average
    annual total return for the since inception period would have been (2.06%)
    for Class C shares. Without the limitation of expenses, the yield for Class
    A, Class B and Class C shares would have been 5.36%, 4.86% and 4.85%,
    respectively.

                   John Hancock Funds - Government Income Fund

(UNAUDITED)

NOTE A -
ACCOUNTING POLICIES

John Hancock Bond Trust (the "Trust") is a diversified open-end management
investment company, registered under the Investment Company Act of 1940, as
amended. The Trust consists of three series: John Hancock Government Income Fund
(the "Fund"), John Hancock High Yield Bond Fund and John Hancock Intermediate
Government Fund. The other two series of the Trust are reported in separate
financial statements. The investment objective of the Fund is to earn a high
level of current income consistent with preservation of capital by investing
primarily in securities that are issued or guaranteed as to principal and
interest by the U.S. government, its agencies or instrumentalities ("U.S.
government securities").

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights to voting, redemptions, dividends and liquidation, except that
certain expenses, subject to the approval of the Trustees, may be applied
differently to each class of shares in accordance with current regulations of
the Securities and Exchange Commission and the Internal Revenue Service.
Shareholders of a class which bears distribution and service expenses under
terms of a distribution plan have exclusive voting rights to that distribution
plan.

      Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in joint repurchase agreement transactions. Aggregate cash
balances are invested in one or more repurchase agreements, whose underlying
securities are obligations of the U.S. government and/or its agencies. The
Fund's custodian bank receives delivery of the underlying securities for the
joint account on the Fund's behalf. The Adviser is responsible for ensuring that
the agreement is fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis for both financial
reporting and federal income tax purposes.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $117,919,246 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. To the extent such carryforwards are used by the
Fund, no capital gains distribution will be made. The carryforwards expire as
follows: May 31, 2002 -- $76,987,244, May 31, 2003 -- $31,030,988, May 31, 2004
- -- $5,561,263 and May 31, 2005 -- $4,339,751. Availability of a certain amount
of loss carryforwards which were acquired on September 15, 1995 and December 4,
1998 in mergers, may be limited in a given year. Additionally, net capital
losses of $4,825,332 attributable to security transactions incurred after
October 31, 1998 are treated as arising on the first day (June 1, 1999) of the
Fund's next taxable year.

DIVIDENDS, INTEREST AND DISTRIBUTIONS Interest income on investment securities
is recorded on the accrual basis. Foreign income may be subject to foreign
withholding taxes, which are accrued as applicable.

      The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund, if any,
with respect to each class of shares will be calculated in the same manner, at
the same time and will be in

=========================NOTES TO FINANCIAL STATEMENTS==========================

                   John Hancock Funds - Government Income Fund

the same amount, except for the effect of expenses that may be applied
differently to each class.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative size of the funds.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund entered into a
syndicated line of credit agreement with various banks that enables the Fund to
participate with other funds managed by the Adviser in an unsecured line of
credit with banks which permit borrowings up to $500 million, collectively.
Interest is charged to each fund, based on its borrowings. In addition, a
commitment fee is charged based on the average daily unused portion of the line
of credit and is allocated among the participating funds. The Fund had no
borrowing activity for the period ended November 30, 1999.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative purposes and/or to hedge against the effects of
fluctuations in interest rates and other market conditions. Buying futures tends
to increase the Fund's exposure to the underlying instrument. Selling futures
tends to decrease the Fund's exposure to the underlying instrument or hedge
other Fund instruments. At the time the Fund enters into a financial futures
contract, it is required to deposit with its custodian a specified amount of
cash or U.S. government securities, known as "initial margin," equal to a
certain percentage of the value of the financial futures contract being traded.
Each day, the futures contract is valued at the official settlement price of the
board of trade or U.S. commodities exchange on which it trades. Subsequent
payments, known as "variation margin," to and from the broker are made on a
daily basis as the market price of the financial futures contract fluctuates.
Daily variation margin adjustments, arising from this "mark to market," are
recorded by the Fund as unrealized gains or losses.

      When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuation imposed by an exchange.

      For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures contracts.

      At November 30, 1999, open positions in financial futures contracts were
as follows:

                                                  UNREALIZED

      At November 30, 1999, the Fund has deposited in a segregated account
$540,000 par value of U.S. Treasury Bond, 15.75%, 11-15-01 and $120,000 par
value of U.S. Treasury Bond, 12.75% 11-15-10, to cover margin requirements on
open financial futures contracts.

                   John Hancock Funds - Government Income Fund

OPTIONS Listed options will be valued at the last quoted sales price on the
exchange on which they are primarily traded. Over-the-counter options will be
valued at the mean between the last asked and bid prices. Upon the writing of a
call or put option, an amount equal to the premium received by the Fund will be
included in the Statement of Assets and Liabilities as an asset and
corresponding liability. The amount of the liability will be subsequently marked
to market to reflect the current market value of the written option.

      The Fund may use option contracts for speculative purposes and/or to
manage its exposure to the bond market. Writing puts and buying calls will tend
to increase the Fund's exposure to the underlying instrument and buying puts and
writing calls will tend to decrease the Fund's exposure to the underlying
instrument, or hedge other Fund investments.

      The maximum exposure to loss for any purchased options will be limited to
the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

      Risks may also arise if counterparties do not perform under the contract's
terms ("credit risk"), or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit and liquidity risks in over-the-counter option contracts, the Fund will
continuously monitor the creditworthiness of all its counterparties.

      At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's period-end
Statement of Assets and Liabilities.

      At November 30, 1999, there were no open option transactions.

NOTE B -
MANAGEMENT FEE, ADMINISTRATIVE SERVICES
AND TRANSACTIONS WITH AFFILIATES AND OTHERS

      Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.65% of the first $200,000,000 of the Fund's
average daily net asset value, (b) 0.625% of the next $300,000,000 and (c) 0.60%
of the Fund's average daily net asset value in excess of $500,000,000. Effective
December 4, 1998, the Adviser agreed to limit the Fund's management fee to 0.50%
of the Fund's daily net assets. Accordingly, the reduction in the management fee
amounted to $455,555 for the period ended November 30, 1999. The Adviser may
terminate this limitation in the future.

      The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the period ended November
30, 1999, net sales charges received with regard to sales of Class A shares
amounted to $110,105. Out of this amount, $5,692 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $49,120
was paid as sales commissions to unrelated broker-dealers and $55,293 was paid
as sales commissions to sales personnel of Signator Investors ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Signator Investors.

      Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended November 30,
1999, contingent deferred sales charges paid to JH Funds amounted to $293,000.

      Class C shares which are redeemed within one year of purchase will be
subject to a CDSC at a rate of 1.00% of the lesser of the current market value
at the time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from the CDSC are paid to JH Funds and are used in whole or
in part to defray its expenses related to providing distribution related
services to the Fund in connection with the sale of Class C shares. For the
period ended November 30,

1999, there were no contingent deferred sales charges.

      In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.25% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

      The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

      The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

      Mr. Stephen L. Brown, Ms. Maureen R. Ford, Ms. Anne C. Hodsdon and Mr.
Richard S. Scipione are directors and/or officers of the Adviser and/or its
affiliates as well as Trustees of the Fund. The compensation of unaffiliated
Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer for
tax purposes their receipt of this compensation under the John Hancock Group of
Funds Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation liability
are recorded on the Fund's books as an other asset. The deferred compensation
liability and the related other asset are always equal and are marked to market
on a periodic basis to reflect any income earned by the investment as well as
any unrealized gains or losses. The investment had no impact on the operations
of the Fund.

NOTE C -

Purchases and proceeds from sales of securities, other than short-term
obligations, during the period ended November 30, 1999, aggregated $411,892,957
and $488,008,586, respectively.

      The cost of investments (excluding the corporate savings account) owned at

NOTE D -
REORGANIZATION

On November 11, 1998, the shareholders of John Hancock Sovereign U.S. Government
Income Fund (JHSGIF) approved a plan of reorganization between JHSGIF and the
Fund, providing for the transfer of substantially all of the assets and
liabilities of JHSGIF to the Fund in exchange solely for Class A and Class B
shares of the Fund. The acquisition of JHSGIF was accounted for as a tax free
exchange of 30,190,113 Class A shares and 9,178,316 Class B shares of the Fund,
which amounted to $285,764,515 and $86,877,349 for Class A and B shares,
respectively, including $11,220,009 of unrealized appreciation, after the close
of business at December 4, 1998. The aggregate net assets of JHSGIF and the Fund
were $372,641,864 and $500,562,839, respectively, immediately before the
acquisition.

===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:

I am delighted that one of my first official duties at John Hancock Funds is to
welcome you to the New Millennium! I wish you all the best for a century filled
with momentous occasions.

Every New Year, of course, provides us with a built-in opportunity to make new
resolutions, or re-commit to old ones. It seems fitting, therefore, that this
special New Year 2000 coincides with a very important, although certainly less
exotic, event.

Starting last October, personalized Social Security statements are being sent to
125 million workers over age 25, showing estimates of the retirement, disability
and survivor benefits that they and their families are eligible to receive now
and in the future.

The statements, to be sent out annually, will provide people with a glimpse of
what they can expect from the government when they retire. This should be
comforting to those who feared that Social Security wouldn't be there for them
at all. But many people also already know that government benefits will only
fulfill a small piece of their retirement needs.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman and Chief Executive Officer,
flush right next to fourth paragraph.]
- --------------------------------------------------------------------------------

The best thing about this massive mailing is that it can serve as a wake-up call
to encourage families to focus more on planning for their financial future.

When you receive your statement, expected to be within three months of your next
birthday, we urge you to read it carefully for accuracy, making sure your annual
earnings history and amounts you have contributed over the years are correct.
Keep in mind that the estimated benefits are precisely that, and that rules and
regulations may change by the time you retire. Also remember that they are not
inflation adjusted, so it would be unrealistic to expect them to have the same
purchasing power in the future as they would today.

We also encourage you to use this mailing as a reason to contact your investment
professional, or to select one if you are not working with somebody. He or she
can help you focus on establishing and maintaining a sound plan to achieve a
comfortable retirement. Together, you should make sure to maximize your
participation in tax-advantaged programs like IRAs and 401(k)s.

The stakes are too high to leave your retirement lifestyle to chance. Congress'
awareness-raising effort is commendable. The next step is yours. Mark the
beginning of the New Millennium by taking it.

Sincerely,


/s/ Maureen R. Ford

MAUREEN R. FORD, VICE CHAIRMAN AND CHIEF EXECUTIVE OFFICER

                    Rising interest rates and inflation fears
                           cause volatile bond market

Inflation concerns grew in the second half of the year, as the U.S. economy
proved unstoppable. Economic growth remained strong, despite mixed signals from
monthly data. Unemployment levels reached a 30-year low, increasing the
potential for wage inflation. Commodity prices, including oil, strengthened. And
global economies began to pick up, removing the deflationary effect that had
somewhat restrained U.S. economic growth in recent years. The dollar also
weakened against the yen, giving foreign investors added incentive to buy U.S.
goods. The Federal Reserve responded to these inflationary pressures by raising
short-term interest rates three times between June 30 and November 16 for a
total increase of three-quarters of a percentage point. Bond investors reacted
quickly to the latest economic news, pushing bond yields higher in advance of
the Fed's moves. The yield on the 30-year Treasury climbed from a low of 5.82%
at the end of May to a high of 6.38% in late October, ending November at 6.29%.

Bond performance review

Rising interest rates weakened bond performance, especially U.S. Treasuries,
which are the most interest-sensitive bonds in the government sector. For the
six months ended November 30, 1999, the Lehman Brothers Treasury Index

"...the U.S. economy proved unstoppable."

in 1999 when prices were cheap."

chart is divided into three sections (from top to left): Short-Term Investments

returned 0.40%. By comparison, bonds with a yield advantage over Treasuries --
namely mortgage bonds and U.S. government agency bonds -- fared better. The
Lehman Brothers Mortgage-Backed Securities Fixed-Rate Index, for example,
returned 1.21% during the same six-month period.

Fund performance

Fortunately, John Hancock Intermediate Government Fund favored both mortgage
bonds and U.S. government agency bonds over Treasuries. For the six months ended
November 30, 1999, the Fund's Class A, Class B and Class C shares had total
returns of 0.82%, 0.44% and 0.43%, respectively, at net asset value. By
comparison, the average intermediate-term government fund returned 0.30% during
the same time, according to Lipper, Inc.(1) Keep in mind that your net asset
value return will differ from the Fund's performance if you were not invested
for the entire period and did not reinvest all distributions. For longer-term
performance information, please see pages six and seven.

Yield advantage

We boosted our stake in mortgage bonds issued by U.S. government agencies early
in 1999 when prices were cheap. During the six-month period, these investments
appreciated nicely as investors looked for higher yields to offset falling bond
prices. Our focus was on GNMA bonds with 7% and 7.5% coupons (or stated interest
rates). Mortgage bonds with current coupons like these are easy to buy and sell,
which is especially important when the market is volatile. Plus, they carry less
prepayment risk -- the risk that homeowners will pay off their mortgages early.
At the end of November, our mortgage stake was 37% of net assets. We also
invested heavily in U.S. government agencies themselves during the period,
buying mainly 30-year securities that offered added yield and liquidity. These
purchases helped us boost non-mortgage U.S. government agencies to 31% of net
assets, up from 24% at the end of May. At the same time, we trimmed Treasuries
to 28% of net assets by selling some 30-year bonds that had performed well. We
held on to 10- and 30-year bonds to help us during periods when the yield curve
- -- the difference in yield between short- and long-term bonds -- flattened.

Duration moves

As always, we shifted the Fund's duration -- a measure of interest-rate
sensitivity -- to keep pace with the market. The longer a bond's duration, the
more its price will fall as interest rates rise -- or rise as interest rates
fall. At the start of the six-month period, the Fund's duration was 4.15 years,
slightly longer than our peer group average. We increased the duration briefly

early June then scaled back to 4.15 years for the rest of the summer. Soon after
the August increase in interest rates, we lengthened duration to 4.25 years,
believing this would be the Fed's last move for the year. We kept duration at
4.25 years through November, somewhat hindering performance as interest rates
climbed higher.

A look ahead

We expect U.S. economic growth to slow, but not until the second half of 2000.
In the meantime, inflation will remain a concern. The Fed will most likely raise
interest rates again sometime in the first quarter of the new year. How much and
when depends largely on fourth-quarter gross domestic product (GDP) numbers,
which come out in January. A strong start to the holiday shopping season may
well drive GDP higher. Employment reports will also be key, especially the
employment cost index -- a measure of wage inflation, unemployment levels and
average hourly earnings. Any further rise in commodity prices or acceleration in
economies overseas could also worsen inflation worries. The bond market hates
inflation -- even the prospect of inflation -- because it erodes the value of
investors' fixed-income earnings. With that in mind, we expect the market to
remain volatile in the first half of the new year. To prepare for this
environment, we plan to shorten the Fund's duration to neutral -- around 4.0
years -- by selling some 30-year Treasury bonds and moving into cash. We may
also sell a small portion of our mortgage and agency investments to capture
recent appreciation. While the road just ahead looks rocky, we expect long-term
bond investors to benefit from the Fed's vigilant efforts to control inflation.

"...we expect long-term bond investors to benefit from the Fed's vigilant
efforts to control inflation."

                              A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Intermediate Government Fund. Total return
measures the change in value of an investment from the beginning to the end of a
period, assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 3%. Class B performance reflects a maximum contingent deferred sales
charge (maximum 3% and declining to 0% over four years). Class C performance
includes a contingent deferred sales charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

Notes to Performance

(1)   Prior to December 5, 1997, the Adviser had agreed to limit the Fund's
      expenses, including management fee, to 0.75% and 1.50% of the average net
      assets attributable to the Class A and Class B shares, respectively.
      Without the reduction of expenses, the average annual total returns for
      the five-year and since inception periods would have been 5.09% and 4.53%,
      respectively, for Class A shares and 5.00% and 4.23%, respectively, for
      Class B shares.

(2)   Not annualized.

                    WHAT HAPPENED TO A $10,000 INVESTMENT...
- --------------------------------------------------------------------------------

The charts on the right show how much a $10,000 investment in the John Hancock
Intermediate Government Fund would be worth, assuming all distributions were
reinvested for the period indicated. For comparison, we've shown the same
$10,000 investment in the Lipper Intermediate U.S. Government Index and Lehman
Brothers Government Bond Index. The Lipper Intermediate U.S. Government Index is
an equally weighted unmanaged index that measures the performance of funds with
at least 65% of their assets in securities issued or guaranteed by the U.S.
government, its agencies or instrumentalities, with dollar-weighted average
maturities of five to ten years. The Lehman Brothers Government Bond Index is an
unmanaged index that measures the performance of U.S.Treasury bonds and U.S.
government agency bonds. It is not possible to invest in an index. Past
performance is not indicative of future results.

                John Hancock Funds - Intermediate Government Fund

(UNAUDITED)

NOTE A -
ACCOUNTING POLICIES

John Hancock Bond Trust (the "Trust") is a diversified, open-end management
investment company, registered under the Investment Company Act of 1940. The
Trust consists of three series: John Hancock Intermediate Government Fund (the
"Fund"), John Hancock Government Income Fund and John Hancock High Yield Bond
Fund. The other two series of the Trust are reported in separate financial
statements. The investment objective of the Fund is to achieve a high level of
current income consistent with preservation of capital and maintenance of
liquidity.

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights to voting, redemption, dividends and liquidation, except that
certain expenses, subject to the approval of the Trustees, may be applied
differently to each class of shares in accordance with current regulations of
the Securities and Exchange Commission. Shareholders of a class which bears
distribution and service expenses under the terms of a distribution plan have
exclusive voting rights to that distribution plan.

      Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement transaction. Aggregate
cash balances are invested in one or more repurchase agreements, whose
underlying securities are obligations of the U.S. government and/or its
agencies. The Fund's custodian bank receives delivery of the underlying
securities for the joint account on the Fund's behalf. The Adviser is
responsible for ensuring that the agreement is fully collateralized at all
times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code.

FEDERAL INCOME TAX The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income or excise tax provision is required.
For federal income tax purposes, the Fund has $14,013,467 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. If such carryforwards are used by the Fund, no
capital gain distributions will be made. The Fund's carryforwards expire as
follows: May 31, 2001 -- $9,365,539, May 31, 2002 -- $427,159, May 31, 2003 --
$1,950,205, May 31, 2004 -- $1,741,681 and May 31, 2005 -- $528,883.
Availability of a certain amount of loss carryforwards which were acquired on
September 22, 1995 and December 5, 1997 in mergers, may be limited in a given
year. Additionally, net capital losses of $1,578,737 attributable to security
transactions incurred after October 31, 1998 are treated as arising on the first
day (June 1, 1999) of the Fund's next taxable year.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

      The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund, if any,
with respect to each class of shares will be calculated in the same manner, at
the same time and will be in the same amount, except for the effect of expenses
that may be applied differently to each class.

==========================NOTES TO FINANCIAL STATEMENTS=========================

                John Hancock Funds - Intermediate Government Fund

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative sizes of the funds.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund entered into a
syndicated line of credit agreement with various banks that enables the Fund to
participate with other funds managed by the Adviser in unsecured lines of credit
with banks which permit borrowings up to $500 million, collectively. Interest is
charged to each fund, based on its borrowing. In addition, a commitment fee is
charged based on the average daily unused portion of the lines of credit and is
allocated among the participating funds. The Fund had no borrowing activity for
the period ended November 30, 1999.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative purposes and/or to hedge against the effects of
fluctuations in interest rates, currency exchange rates and other market
conditions. Buying futures tends to increase the Fund's exposure to the
underlying instrument. Selling futures tends to decrease the Fund's exposure to
the underlying instrument or hedge other Fund instruments. At the time the Fund
enters into a financial futures contract, it will be required to deposit with
its custodian a specified amount of cash or U.S. government securities, known as
"initial margin," equal to a certain percentage of the value of the financial
futures contract being traded. Each day, the futures contract is valued at the
official settlement price on the board of trade or U.S. commodities exchange on
which it trades. Subsequent payments to and from the broker, known as "variation
margin," are made on a daily basis as the market price of the financial futures
contract fluctuates. Daily variation margin adjustments, arising from this "mark
to market," will be recorded by the Fund as unrealized gains or losses.

      When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuation imposed by an exchange.

      For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures contracts.

      At November 30, 1999, there were no open financial futures contracts.

OPTIONS The Fund may purchase or sell option contracts. Listed options will be
valued at the last quoted sales price on the exchange on which they are
primarily traded. Over-the-counter options are valued at the mean between the
last bid and asked prices. Upon the writing of a call or put option, an amount
equal to the premium received by the Fund will be included in the Statement of
Assets and Liabilities as an asset and corresponding liability. The amount of
the liability will be subsequently market to market to reflect the current
market value of the written option.

      The Fund may use option contracts to manage its exposure to the stock
market. Writing puts and buying calls will tend to increase the Fund's exposure
to the underlying instrument and buying puts and writing calls will tend to
decrease the Fund's exposure to the underlying instrument, or hedge other Fund
investments.

      The maximum exposure to loss for any purchased options will be limited to
the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual


                                       17
<PAGE>
==========================NOTES TO FINANCIAL STATEMENTS=========================

                John Hancock Funds - Intermediate Government Fund

exposure will be limited to the change in value of the contract over the period
the contract remains open.

      Risks may also arise if counterparties do not perform under the contract's
terms ("credit risk"), or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit and liquidity risks in over-the-counter option contracts, the Fund will
continuously monitor the creditworthiness of all its counterparties.

      At any particular time, except for purchase options, market or credit risk
may involve amounts in excess of those reflected in the Fund's period-ended
Statement of Assets and Liabilities.

      At November 30, 1999, there were no open written option transactions.

NOTE B -
MANAGEMENT FEE, ADMINISTRATIVE SERVICES
AND TRANSACTIONS WITH AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent on
an annual basis to 0.40% of the Fund's average daily net asset value.

      The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the period ended November
30, 1999, net sales charges received with regard to sales of Class A shares
amounted to $48,293. Out of this amount, $5,560 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $24,663
was paid as sales commissions to unrelated broker-dealers and $18,070 was paid
as sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Signator Investors.

      Class B shares which are redeemed within four years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 3.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended November 30,
1999, contingent deferred sales charges amounted to $79,398.

      Class C shares which are redeemed within one year of purchase will be
subject to a CDSC at a rate of 1.00% of the lesser of the current market value
at the time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from the CDSC are paid to JH Funds and are used in whole or
in part to defray its expenses related to providing distribution related
services to the Fund in connection with the sale of Class C shares. For the
period ended November 30, 1999, contingent deferred sales charges paid to JH
Funds amounted to $666.

      In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution Plan with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.25% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

      The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

      The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

      Mr. Stephen L. Brown, Ms. Maureen R. Ford, Ms. Anne C. Hodsdon and Mr.
Richard S. Scipione are directors and/or officers of the Adviser and/or its
affiliates, as well as Trustees of the Fund. The compensation

of unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may
elect to defer for tax purposes their receipt of this compensation under the
John Hancock Group of Funds Deferred Compensation Plan. The Fund makes
investments into other John Hancock funds, as applicable, to cover its liability
for the deferred compensation. Investments to cover the Fund's deferred
compensation liability are recorded on the Fund's books as an other asset. The
deferred compensation liability and the related other asset are always equal and
are marked to market on a periodic basis to reflect any income earned by the
investment as well as any unrealized gains or losses. The investment had no
impact on the operations of the Fund.

NOTE C -
